Order book

A single-file, fully offline app for tracking orders and invoicing them. No server, no accounts, no internet needed — just open index.html in a browser.

Features

• Orders: order number (auto-suggests the next one), date, quantity, price per order, customer or note. Value is worked out for you.
• Paid tracking: click to stamp an order PAID, or mark several at once.
• Summary: order count, units, total value, paid and outstanding. Follows your filters (status, month, search).
• Invoices: pick orders, add bill-to details, and see a live preview. Invoice numbers auto-increment and due dates come from your payment terms. Optional VAT.
• Branding: logo, company name, address, contact details, VAT/company number, payment details and footer.
• PDF export: generated in the browser (jsPDF is bundled in the file).
• Email: opens your mail app or webmail (Gmail, Outlook, custom link) with the recipient, subject and message filled in. The PDF downloads alongside, ready to attach.
• CSV export of orders.
• Backup / restore of all data as a JSON file.

Running it

git clone https://github.com/<you>/order-book.git
xdg-open order-book/index.html

Or serve it locally so the browser always sees the same address:

cd order-book && python3 -m http.server 8080
# then open http://localhost:8080

Where your data lives

Everything is stored in the browser's local storage, not in this repo. That means:

• Data is tied to one browser and one address. Opening the file from a different path, or in a different browser, shows an empty app.
• Clearing browsing data wipes it.
• Use Settings → Backup → Download backup regularly. Restore it on any machine with Settings → Restore from backup.

Backup files contain customer and invoice details. .gitignore keeps them out of the repo — don't commit them, especially if the repo is public.

Hosting on GitHub Pages (optional)

Repo → Settings → Pages → Source: Deploy from a branch, main / root. The app will be at https://<you>.github.io/order-book/.

The page is public but your data isn't. It stays in each visitor's own browser, so nobody else can see your orders. Pages on a private repo needs a paid GitHub plan.
